FOREWORD

This book discusses a new interpretation of the nature of obesity, and while it does not advocate yet another fancy slimming diet it does describe a method of treatment which has grown out of theoretical considerations based on clinical observation.

What I have to say is an essence of views distilled out of forty years of grappling with the fundamental problems of obesity, its causes, its symptoms, and its very nature. In these many years of specialized work, thousands of cases have passed through my hands and were carefully studied. Every new theory, every new method, every promising lead was considered, experimentally screened and critically evaluated as soon as it became known. But invariably the results were disappointing and lacking in uniformity.

I felt that we were merely nibbling at the fringe of a great problem, as, indeed, do most serious students of overweight. We have grown pretty sure that the tendency to accumulate abnormal fat is a very definite metabolic disorder, much as is, for instance, diabetes. Yet the localization and the nature of this disorder remained a mystery. Every new approach seemed to lead into a blind alley, and though patients were told that they are fat because they eat too much, we believed that this is neither the whole truth nor the last word in the matter.

Refusing to be side-tracked by an all too facile interpretation of obesity, I have always held that overeating is the result of the disorder, not its cause, and that we can make little headway until we can build for ourselves some sort of theoretical structure with which to explain the condition. Whether such a structure represents the truth is not important at this moment. What it must do is to give us an intellectually satisfying interpretation of what is happening in the obese body. It must also be able to withstand the onslaught of all hitherto known clinical facts and furnish a hard background against which the results of treatment can be accurately assessed.

To me this requirement seems basic, and it has always been the center of my interest. In dealing with obese patients it became a habit to register and order every clinical experience as if it were an odd looking piece of a jig-saw puzzle. And then, as in a jig-saw puzzle, little clusters of fragments began to form, though they seemed to fit in nowhere. As the years passed these clusters grew bigger and started to amalgamate until, about sixteen years ago, a complete picture became dimly discernible. This picture was, and still is, dotted with gaps for which I cannot find the pieces, but I do now feel that a theoretical structure is visible as a whole.

With mounting experience more and more facts seemed to fit snugly into the new framework, and when then a treatment based on such speculations showed consistently satisfactory results, I was sure that some practical advance had been made, regardless of whether the theoretical interpretation of these results is correct or not.

The clinical results of the new treatment have been published in scientific journal * and these reports have been generally well received by the profession, but the very nature of a scientific article does not permit the full presentation of new theoretical concepts nor is there room to discuss the finer points of technique and the reasons for observing them.

During the 16 years that have elapsed since I first published my findings, I have had many hundreds of inquiries from research institutes, doctors and patients. Hitherto I could only refer those interested to my scientific papers, though I realized that these did not contain sufficient information to enable doctors to conduct the new treatment satisfactorily. Those who tried were obliged to gain their own experience through the many trials and errors which I have long since overcome.

Doctors from all over the world have come to Italy to study the method, first hand in my clinic in the Salvator Mundi International Hospital in Rome. For some of them the time they could spare has been too short to get a full grasp of the technique, and in any case the number of those whom I have been able to meet personally is small compared with the many requests for further detailed information which keep coming in. I have tried to keep up with these demands by correspondence, but the volume of this work has become unmanageable and that is one excuse for writing this book.

In dealing with a disorder in which the patient must take an active part in the treatment, it is, I believe, essential that he or she have an understanding of what is being done and why. Only then can there be intelligent cooperation between physician and patient. In order to avoid writing two books, one for the physician and another for the patient - a prospect which would probably have resulted in no book at all - I have tried to meet the requirements of both in a single book. This is a rather difficult enterprise in which I may not have succeeded. The expert will grumble about long-windedness, while the lay-reader may occasionally have to look up an unfamiliar word in the glossary provided for him.

To make the text more readable I shall be unashamedly authoritative and avoid all the hedging and tentativeness with which it is customary to express new scientific concepts grown out of clinical experience and not as yet confirmed by clear-cut laboratory experiments. Thus when I make what reads like a factual statement, the professional reader may have to translate into: clinical experience seems to suggest that such and such an observation might be tentatively explained by such and such a working hypothesis, requiring a vast amount of further research before the hypothesis can be considered a valid theory. If we can from the outset establish this as a mutually accepted convention, I hope to avoid being accused of speculative exuberance.

THE NATURE OF OBESITY

Obesity a Disorder

As a basis for our discussion we postulate that obesity in all its many forms is due to an abnormal functioning of some part of the body and that every ounce of abnormally accumulated fat is always the result of the same disorder of certain regulatory mechanisms. Persons suffering from this particular disorder will get fat regardless of whether they eat excessively, normally or less than normal. A person who is free of the disorder will never get fat, even if he frequently overeats.

Those in whom the disorder is severe will accumulate fat very rapidly, those in whom it is moderate will gradually increase in weight and those in whom it is mild may be able to keep their excess weight stationary for long periods. In all these cases a loss of weight brought about by dieting, treatments with thyroid, appetite-reducing drugs, laxatives, violent exercise, massage, baths, etc., is only temporary and will be rapidly regained as soon as the reducing regimen is relaxed. The reason is simply that none of these measures corrects the basic disorder.

While there are great variations in the severity of obesity, we shall consider all the different forms in both sexes and at all ages as always being due to the same disorder. Variations in form would then be partly a matter of degree, partly an inherited bodily constitution and partly the result of a secondary involvement of endocrine glands such as the pituitary, the thyroid, the adrenals or the sex glands. On the other hand, we postulate that no deficiency of any of these glands can ever directly produce the common disorder known as obesity.

If this reasoning is correct, it follows that a treatment aimed at curing the disorder must be equally effective in both sexes, at all ages and in all forms of obesity. Unless this is so, we are entitled to harbor grave doubts as to whether a given treatment corrects the underlying disorder. Moreover, any claim that the disorder has been corrected must be substantiated by the ability of the patient to eat normally of any food he pleases without regaining abnormal fat after treatment. Only if these conditions are fulfilled can we legitimately speak of curing obesity rather than of reducing weight.

Our problem thus presents itself as an enquiry into the localization and the nature of the disorder which leads to obesity. The history of this enquiry is a long series of high hopes and bitter disappointments.

The History of Obesity

There was a time, not so long ago, when obesity was considered a sign of health and prosperity in man and of beauty, amorousness and fecundity in women. This attitude probably dates back to Neolithic times, about 8000 years ago; when for the first time in the history of culture, man began to own property, domestic animals, arable land, houses, pottery and metal tools. Before that, with the possible exception of some races such as the Hottentots, obesity was almost non-existent, as it still is in all wild animals and most primitive races.

Today obesity is extremely common among all civilized races, because a disposition to the disorder can be inherited. Wherever abnormal fat was regarded as an asset, sexual selection tended to propagate the trait. It is only in very recent times that manifest obesity has lost some of its allure, though the cult of the outsize bust - always a sign of latent obesity - shows that the trend still lingers on.

The Significance of Regular Meals

In the early Neolithic times another change took place which may well account for the fact that today nearly all inherited dispositions sooner or later develop into manifest obesity. This change was the institution of regular meals. In pre-Neolithic times, man ate only when he was hungry and on1y as much as he required too still the pangs of hunger. Moreover, much of his food was raw and all of it was unrefined. He roasted his meat, but he did not boil it, as he had no pots, and what little he may have grubbed from the Earth and picked from the trees, he ate as he went along.

The whole structure of man's omnivorous digestive tract is, like that of an ape, rat or pig, adjusted to the continual nibbling of tidbits. It is not suited to occasional gorging as is, for instance, the intestine of the carnivorous cat family. Thus the institution of regular meals, particularly of food rendered rapidly assimilable, placed a great burden on modern man's ability to cope with large quantities of food suddenly pouring into his system from the intestinal tract.

The institution of regular meals meant that man had to eat more than his body required at the moment of eating so as to tide him over until the next meal. Food rendered easily digestible suddenly flooded his body with nourishment of which he was in no need at the moment. Somehow, somewhere this surplus had to be stored.

Three Kinds of Fat

In the human body we can distinguish three kinds of fat. The first is the structural fat which fills the gaps between various organs, a sort of packing material. Structural fat also performs such important functions as bedding the kidneys in soft elastic tissue, protecting the coronary arteries and keeping the skin smooth and taut. It also provides the springy cushion of hard fat under the bones of the feet, without which we would be unable to walk.

The second type of fat is a normal reserve of fuel upon which the body can freely draw when the nutritional income from the intestinal tract is insufficient to meet the demand. Such normal reserves are localized all over the body. Fat is a substance which packs the highest caloric value into the smallest space so that normal reserves of fuel for muscular activity and the maintenance of body temperature can be most economically stored in this form. Both these types of fat, structural and reserve, are normal, and even if the body stocks them to capacity this can never be called obesity.

But there is a third type of fat which is entirely abnormal. It is the accumulation of such fat, and of such fat only, from which the overweight patient suffers. This abnormal fat is also a potential reserve of fuel, but unlike the normal reserves it is not available to the body in a nutritional emergency. It is, so to speak, locked away in a fixed deposit and is not kept in a current account, as are the normal reserves.

When an obese patient tries to reduce by starving himself, he will first lose his normal fat reserves. When these are exhausted he begins to burn up structural fat, and only as a last resort will the body yield its abnormal reserves, though by that time the patient usually feels so weak and hungry that the diet is abandoned. It is just for this reason that obese patients complain that when they diet they lose the wrong fat. They feel famished and tired and their face becomes drawn and haggard, but their belly, hips, thighs and upper arms show little improvement. The fat they have come to detest stays on and the fat they need to cover their bones gets less and less. Their skin wrinkles and they look old and miserable. And that is one of the most frustrating and depressing experiences a human being can have.

Injustice to the Obese

When then obese patients are accused of cheating, gluttony, lack of will power, greed and sexual complexes, the strong become indignant and decide that modern medicine is a fraud and its representatives fools, while the weak just give up the struggle in despair. In either case the result is the same: a further gain in weight, resignation to an abominable fate and the resolution at least to live tolerably the short span allotted to them - a fig for doctors and insurance companies.

Obese patients only feel physically well as long as they are stationary or gaining weight. They may feel guilty, owing to the lethargy and indolence always associated with obesity. They may feel ashamed of what they have been led to believe is a lack of control. They may feel horrified by the appearance of their nude body and the tightness of their clothes. But they have a primitive feeling of animal content which turns to misery and suffering as soon as they make a resolute attempt to reduce. For this there are sound reasons.

In the first place, more caloric energy is required to keep a large body at a certain temperature than to heat a small body. Secondly the muscular effort of moving a heavy body is greater than in the case of a light body. The muscular effort consumes Calories which must be provided by food. Thus, all other factors being equal, a fat person requires more food than a lean one. One might therefore reason that if a fat person eats only the additional food his body requires he should be able to keep his weight stationary. Yet every physician who has studied obese patients under rigorously controlled conditions knows that this is not true. Many obese patients actually gain weight on a diet which is calorically deficient for their basic needs. There must thus be some other mechanism at work.

Glandular Theories

At one time it was thought that this mechanism might be concerned with the sex glands. Such a connection was suggested by the fact that many juvenile obese patients show an under-development of the sex organs. The middle-age spread in men and the tendency of many women to put on weight in the menopause seemed to indicate a causal connection between diminishing sex function and overweight. Yet, when highly active sex hormones became available, it was found that their administration had no effect whatsoever on obesity. The sex glands could therefore not be the seat of the disorder.

The Thyroid Gland

When it was discovered that the thyroid gland controls the rate at which body-fuel is consumed, it was thought that by administering thyroid gland to obese patients their abnormal fat deposits could be burned up more rapidly. This too proved to be entirely disappointing, because as we now know, these abnormal deposits take no part in the body's energy-turnover - they are inaccessibly locked away. Thyroid medication merely forces the body to consume its normal fat reserves, which are already depleted in obese patients, and then to break down structurally essential fat without touching the abnormal deposits. In this way a patient may be brought to the brink of starvation in spite of having a hundred pounds of fat to spare. Thus any weight loss brought about by thyroid medication is always at the expense of fat of which the body is in dire need.

While the majority of obese patients have a perfectly normal thyroid gland and some even have an overactive thyroid, one also occasionally sees a case with a real thyroid deficiency. In such cases, treatment with thyroid brings about a small loss of weight, but this is not due to the loss of any abnormal fat. It is entirely the result of the elimination of a mucoid substance, called myxedema, which the body accumulates when there is a marked primary thyroid deficiency. Moreover, patients suffering only from a severe lack of thyroid hormone never become obese in the true sense. Possibly also the observation that normal persons - though not the obese - lose weight rapidly when their thyroid becomes overactive may have contributed to the false notion that thyroid deficiency and obesity are connected. Much misunderstanding about the supposed role of the thyroid gland in obesity is still met with, and it is now really high time that thyroid preparations be once and for all struck off the list of remedies for obesity. This is particularly so because giving thyroid gland to an obese patient whose thyroid is either normal or overactive, besides being useless, is decidedly dangerous.

The Pituitary Gland

The next gland to be falsely incriminated was the anterior lobe of the pituitary or hypophysis. This most important gland lies well protected in a bony capsule at the base of the skull. It has a vast number of functions in the body, among which is the regulation of all the other important endocrine glands. The fact that various signs of anterior pituitary deficiency are often associated with obesity raised the hope that the seat of the disorder might be in this gland. But although a large number of pituitary hormones have been isolated and many extracts of the gland prepared, not a single one or any combination of such factors proved to be of any value in the treatment of obesity. Quite recently, however, a fat-mobilizing factor has been found in pituitary glands, but it is still too early to say whether this factor is destined to play a role in the treatment of obesity.

The Adrenals

Recently, a long series of brilliant discoveries concerning the working of the adrenal or suprarenal glands, small bodies which sit atop the kidneys, have created tremendous interest. This interest also turned to the problem of obesity when it was discovered that a condition which in some respects resembles a severe case of obesity - the so-called Cushing's Syndrome - was caused by a glandular new-growth of the adrenals or by their excessive stimulation with ACTH, which is the pituitary hormone governing the activity of the outer rind or cortex of the adrenals.

When we learned that an abnormal stimulation of the adrenal cortex could produce signs that resemble true obesity, this knowledge furnished no practical means of treating obesity by decreasing the activity of the adrenal cortex. There is no evidence to suggest that in obesity there is any excess of adrenocortical activity; in fact, all the evidence points to the contrary. There seems to be rather a lack of adrenocortical function and a decrease in the secretion of ACTH from the anterior pituitary lobe. *

So here again our search for the mechanism which produces obesity led us into a blind alley. Recently, many students of obesity have reverted to the nihilistic attitude that obesity is caused simply by overeating and that it can only be cured by under eating.

The Diencephalon or Hypothalamus

For those of us who refused to be discouraged there remained one slight hope. Buried deep down in the massive human brain there is a part which we have in common with all vertebrate animals, the so-called diencephalon. It is a very primitive part of the brain and has in man been almost smothered by the huge masses of nervous tissue with which we think, reason and voluntarily move our body. The diencephalon is the part from which the central nervous system controls all the automatic animal functions of the body, such as breathing, the heart beat, digestion, sleep, sex, the urinary system, the autonomous or vegetative nervous system and via the pituitary the whole interplay of the endocrine glands.

* There is some clinical evidence to suggest that those symptoms of Cushing's Syndrome which resemble true obesity are caused by the same mechanism which causes common obesity, while the other symptoms of the syndrome are directly due to adrenocortical dysfunction.

It was therefore not unreasonable to suppose that the complex operation of storing and issuing fuel to the body might also be controlled by the diencephalon. It has long been known that the content of sugar - another form of fuel - in the blood depends on a certain nervous center in the diencephalon. When this center is destroyed in laboratory animals, they develop a condition rather similar to human stable diabetes. It has also long been known that the destruction of another diencephalic center produces a voracious appetite and a rapid gain in weight in animals which never get fat spontaneously.

The Fat-bank

Assuming that in man such a center controlling the movement of fat does exist, its function would have to be much like that of a bank. When the body assimilates from the intestinal tract more fuel than it needs at the moment, this surplus is deposited in what may be compared with a current account. Out of this account it can always be withdrawn as required. All normal fat reserves are in such a current account, and it is probable that a diencephalic center manages the deposits and withdrawals.

When now, for reasons which will be discussed later, the deposits grow rapidly while small withdrawals become more frequent, a point may be reached which goes beyond the diencephalon's banking capacity. Just as a banker might suggest to a wealthy client that instead of accumulating a large and unmanageable current account he should invest his surplus capital, the body appears to establish a fixed deposit into which all surplus funds go but from which they can no longer be withdrawn by the procedure used in a current account. In this way the diencephalic "fat-bank" frees itself from all work which goes beyond its normal banking capacity. The onset of obesity dates from the moment the diencephalon adopts this labor-saving ruse. Once a fixed deposit has been established the normal fat reserves are held at a minimum, while every available surplus is locked away in the fixed deposit and is therefore taken out of normal circulation.

THREE BASIC CAUSES OF OBESITY:

(1) The Inherited Factor

Assuming that there is a limit to the diencephalon's fat banking capacity, it follows that there are three basic ways in which obesity can become manifest. The first is that the fat-banking capacity is abnormally low from birth. Such a congenitally low diencephalic capacity would then represent the inherited factor in obesity. When this abnormal trait is markedly present, obesity will develop at an early age in spite of normal feeding; this could explain why among brothers and sisters eating the same food at the same table some become obese and others do not.

(2) Other Diencephalic Disorders

The second way in which obesity can become established is the lowering of a previously normal fat-banking capacity owing to some other diencephalic disorder. It seems to be a general rule that when one of the many diencephalic centers is particularly overtaxed; it tries to increase its capacity at the expense of other centers.

In the menopause and after castration the hormones previously produced in the sex glands no longer circulate in the body. In the presence of normally functioning sex glands their hormones act as a brake on the secretion of the sex gland stimulating hormones of the anterior pituitary. When this brake is removed the anterior pituitary enormously increases its output of these sex gland stimulating hormones, though they are now no longer effective. In the absence of any response from the non-functioning or missing sex glands, there is nothing to stop the anterior pituitary from producing more and more of these hormones. This situation causes an excessive strain on the diencephalic center which controls the function of the anterior pituitary. In order to cope with this additional burden the center appears to draw more and more energy away from other centers, such as those concerned with emotional stability, the blood circulation (hot flushes) and other autonomous nervous regulations, particularly also from the not so vitally important fat-bank.

The so-called stable type of diabetes heavily involves the diencephalic blood sugar regulating center. The diencephalon tries to meet this abnormal load by switching energy destined for the fat-bank over to the sugar-regulating center, with the result that the fat-banking capacity is reduced to the point at which it is forced to establish a fixed deposit and thus initiate the disorder we call obesity. In this case one would have to consider the diabetes the primary cause of the obesity, but it is also possible that the process is reversed in the sense that a deficient or overworked fat-center draws energy from the sugar-center, in which case the obesity would be the cause of that type of diabetes in which the pancreas is not primarily involved. Finally, it is conceivable that in Cushing's syndrome those symptoms which resemble obesity are entirely due to the withdrawal of energy from the diencephalic fat-bank in order to make it available to the highly disturbed center which governs the anterior pituitary-adrenocortical system.

Whether obesity is caused by a marked inherited deficiency of the fat-center or by some entirely different diencephalic regulatory disorder, its insurgence obviously has nothing to do with overeating and in either case obesity is certain to develop regardless of dietary restrictions. In these cases any enforced food deficit is made up from essential fat reserves and normal structural fat, much to the disadvantage of the patient's general health.

(3) The Exhaustion of the Fat-bank

But there is still a third way in which obesity can become established, and that is when a presumably normal fat-center is suddenly - the emphasis is on suddenly - called upon to deal with an enormous influx of food far in excess of momentary requirements. At first glance it does seem that here we have a straight-forward case of overeating being responsible for obesity, but on further analysis it soon becomes clear that the relation of cause and effect is not so simple. In the first place we are merely assuming that the capacity of the fat-center is normal while it is possible and even probable that only persons who have some inherited trait in this direction can become obese merely by overeating.

Secondly, in many of these cases the amount of food eaten remains the same and it is only the consumption of fuel which is suddenly decreased, as when an athlete is confined to bed for many weeks with a broken bone or when a man leading a highly active life is suddenly tied to his desk in an office and to television at home. Similarly, when a person, grown up in a cold climate, is transferred to a tropical country and continues to eat as before, he may develop obesity because in the heat far less fuel is required to maintain the normal body temperature.

When a person suffers a long period of privation, be it due to chronic illness, poverty, famine or the exigencies of war, his diencephalic regulations adjust themselves to some extent to the low food intake. When then suddenly these conditions change and he is free to eat all the food he wants, this is liable to overwhelm his fat-regulating center. During the last war about 6000 grossly underfed Polish refugees who had spent harrowing years in Russia were transferred to a camp in India where they were well housed, given normal British army rations and some cash to buy a few extras. Within about three months, 85% were suffering from obesity.

In a person eating coarse and unrefined food, the digestion is slow and only a little nourishment at a time is assimilated from the intestinal tract. When such a person is suddenly able to obtain highly refined foods such as sugar, white flour, butter and oil these are so rapidly digested and assimilated that the rush of incoming fuel which occurs at every meal may eventually overpower the diecenphalic regulatory mechanisms and thus lead to obesity. This is commonly seen in the poor man who suddenly becomes rich enough to buy the more expensive refined foods, though his total caloric intake remains the same or is even less than before.

Psychological Aspects

Much has been written about the psychological aspects of obesity. Among its many functions the diencephalon is also the seat of our primitive animal instincts, and just as in an emergency it can switch energy from one center to another, so it seems to be able to transfer pressure from one instinct to another. Thus, a lonely and unhappy person deprived of all emotional comfort and of all instinct gratification except the stilling of hunger and thirst can use these as outlets for pent up instinct pressure and so develop obesity. Yet once that has happened, no amount of psychotherapy or analysis, happiness, company or the gratification of other instincts will correct the condition.

Compulsive Eating

No end of injustice is done to obese patients by accusing them of compulsive eating, which is a form of diverted sex-gratification. Most obese patients do not suffer from compulsive eating; they suffer genuine hunger - real, gnawing, torturing hunger - which has nothing whatever to do with compulsive eating. Even their sudden desire for sweets is merely the result of the experience that sweets, pastries and alcohol will most rapidly of all foods allay the pangs of hunger. This has nothing to do with diverted instincts.

On the other hand, compulsive eating does occur in some obese patients, particularly in girls in their late teens or early twenties. Compulsive eating differs fundamentally from the obese patient's greater need for food. It comes on in attacks and is never associated with real hunger, a fact which is readily admitted by the patients. They only feel a feral desire to stuff. Two pounds of chocolates may be devoured in a few minutes; cold, greasy food from the refrigerator, stale bread, leftovers on stacked plates, almost anything edible is crammed down with terrifying speed and ferocity.

I have occasionally been able to watch such an attack without the patient's knowledge, and it is a frightening, ugly spectacle to behold, even if one does realize that mechanisms entirely beyond the patient's control are at work. A careful enquiry into what may have brought on such an attack almost invariably reveals that it is preceded by a strong unresolved sex-stimulation, the higher centers of the brain having blocked primitive diencephalic instinct gratification. The pressure is then let off through another primitive channel, which is oral gratification. In my experience the only thing that will cure this condition is uninhibited sex, a therapeutic procedure which is hardly ever feasible, for if it were, the patient would have adopted it without professional prompting, nor would this in any way correct the associated obesity. It would only raise new and often greater problems if used as a therapeutic measure.

Patients suffering from real compulsive eating are comparatively rare. In my practice they constitute about 1-2%. Treating them for obesity is a heartrending job. They do perfectly well between attacks, but a single bout occurring while under treatment may annul several weeks of therapy. Little wonder that such patients become discouraged. In these cases I have found that psychotherapy may make the patient fully understand the mechanism, but it does nothing to stop it. Perhaps society's growing sexual permissiveness will make compulsive eating even rarer.

Whether a patient is really suffering from compulsive eating or not is hard to decide before treatment because many obese patients think that their desire for food - to them unmotivated - is due to compulsive eating, while all the time it is merely a greater need for food. The only way to find out is to treat such patients. Those that suffer from real compulsive eating continue to have such attacks, while those who are not compulsive eaters never get an attack during treatment.

Reluctance to Lose Weight

Some patients are deeply attached to their fat and cannot bear the thought of losing it. If they are intelligent, popular and successful in spite of their handicap, this is a source of pride. Some fat girls look upon their condition as a safeguard against erotic involvements, of which they are afraid. They work out a pattern of life in which their obesity plays a determining role and then become reluctant to upset this pattern and face a new kind of life which will be entirely different after their figure has become normal and often very attractive. They fear that people will like them - or be jealous - on account of their figure rather than be attracted by their intelligence or character only. Some have a feeling that reducing means giving up an almost cherished and intimate part of themselves. In many of these cases psychotherapy can be helpful, as it enables these patients to see the whole situation in the full light of consciousness. An affectionate attachment to abnormal fat is usually seen in patients who became obese in childhood, but this is not necessarily so.

In all other cases the best psychotherapy can do in the usual treatment of obesity is to render the burden of hunger and never-ending dietary restrictions slightly more tolerable. Patients who have successfully established an erotic transfer to their psychiatrist are often better able to bear their suffering as a secret labor of love.

There are thus a large number of ways in which obesity can be initiated, though the disorder itself is always due to the same mechanism, an inadequacy of the diencephalic fat-center and the laying down of abnormally fixed fat deposits in abnormal places. This means that once obesity has become established, it can no more be cured by eliminating those factors which brought it on than a fire can be extinguished by removing the cause of the conflagration. Thus a discussion of the various ways in which obesity can become established is useful from a preventative point of view, but it has no bearing on the treatment of the established condition. The elimination of factors which are clearly hastening the course of the disorder may slow down its progress or even halt it, but they can never correct it.

Not by Weight alone...

Weight alone is not a satisfactory criterion by which to judge whether a person is suffering from the disorder we call obesity or not. Every physician is familiar with the sylphlike lady who enters the consulting room and declares emphatically that she is getting horribly fat and wishes to reduce. Many an honest and sympathetic physician at once concludes that he is dealing with a "nut." If he is busy he will give her short shrift, but if he has time he will weigh her and show her tables to prove that she is actually underweight.

I have never yet seen or heard of such a lady being convinced by either procedure. The reason is that in my experience the lady is nearly always right and the doctor wrong. When such a patient is carefully examined one finds many signs of potential obesity, which is just about to become manifest as overweight. The patient distinctly feels that something is wrong with her, that a subtle change is taking place in her body, and this alarms her.

There are a number of signs and symptoms which are characteristic of obesity. In manifest obesity many and often all these signs and symptoms are present. In latent or just beginning cases some are always found, and it should be a rule that if two or more of the bodily signs are present, the case must be regarded as one that needs immediate help.

Signs and symptoms of obesity

The bodily signs may be divided into such as have developed before puberty, indicating a strong inherited factor, and those which develop at the onset of manifest disorder. Early signs are a disproportionately large size of the two upper front teeth, the first incisor, or a dimple on both sides of the sacral bone just above the buttocks. When the arms are outstretched with the palms upward, the forearms appear sharply angled outward from the upper arms. The same applies to the lower extremities. The patient cannot bring his feet together without the knees overlapping; he is, in fact, knock-kneed.

The beginning accumulation of abnormal fat shows as a little pad just below the nape of the neck, colloquially known as the Duchess' Hump. There is a triangular fatty bulge in front of the armpit when the arm is held against the body. When the skin is stretched by fat rapidly accumulating under it, it may split in the lower layers. When large and fresh, such tears are purple, but later they are transformed into white scar-tissue. Such striation, as it is called, commonly occurs on the abdomen of women during pregnancy, but in obesity it is frequently found on the breasts, the hips and occasionally on the shoulders. In many cases striation is so fine that the small white lines are only just visible. They are always a sure sign of obesity, and though this may be slight at the time of examination such patients can usually remember a period in their childhood when they were excessively chubby.

Another typical sign is a pad of fat on the insides of the knees, a spot where normal fat reserves are never stored. There may be a fold of skin over the pubic area and another fold may stretch round both sides of the chest, where a loose roll of fat can be picked up between two fingers. In the male an excessive accumulation of fat in the breasts is always indicative, while in the female the breast is usually, but not necessarily, large. Obviously excessive fat on the abdomen, the hips, thighs, upper arms, chin and shoulders are characteristic, and it is important to remember that any number of these signs may be present in persons whose weight is statistically normal; particularly if they are dieting on their own with iron determination.

Common clinical symptoms which are indicative only in their association and in the frame of the whole clinical picture are: frequent headaches, rheumatic pains without detectable bony abnormality; a feeling of laziness and lethargy, often both physical and mental and frequently associated with insomnia, the patients saying that all they want is to rest; the frightening feeling of being famished and sometimes weak with hunger two to three hours after a hearty meal and an irresistible yearning for sweets and starchy food which often overcomes the patient quite suddenly and is sometimes substituted by a desire for alcohol; constipation and a spastic or irritable colon are unusually common among the obese, and so are menstrual disorders.

Returning once more to our sylphlike lady, we can say that a combination of some of these symptoms with a few of the typical bodily signs is sufficient evidence to take her case seriously. A human figure, male or female, can only be judged in the nude; any opinion based on the dressed appearance can be quite fantastically wide off the mark, and I feel myself driven to the conclusion that apart from frankly psychotic patients such as cases of anorexia nervosa a "morbid weight fixation" does not exist. I have yet to see a patient who continues to complain after the figure has been rendered normal by adequate treatment.

The Emaciated Lady

I remember the case of a lady who was escorted into my consulting room while I was telephoning. She sat down in front of my desk, and when I looked up to greet her I saw the typical picture of advanced emaciation. Her dry skin hung loosely over the bones of her face, her neck was scrawny and collarbones and ribs stuck out from deep hollows. I immediately thought of cancer and decided to which of my colleagues at the hospital I would refer her. Indeed, I felt a little annoyed that my assistant had not explained to her that her case did not fall under my specialty. In answer to my query as to what I could do for her, she replied that she wanted to reduce. I tried to hide my surprise, but she must have noted a fleeting expression, for she smiled and said "I know that you think I'm mad, but just wait." With that she rose and came round to my side of the desk. Jutting out from a tiny waist she had enormous hips and thighs.

By using a technique which will presently be described, the abnormal fat on her hips was transferred to the rest of her body which had been emaciated by months of very severe dieting. At the end of a treatment lasting five weeks, she, a small woman, had lost 8 inches round her hips, while her face looked fresh and florid, the ribs were no longer visible and her weight was the same to the ounce as it had been at the first consultation.

Fat but not Obese

While a person who is statistically underweight may still be suffering from the disorder which causes obesity, it is also possible for a person to be statistically overweight without suffering from obesity. For such persons weight is no problem, as they can gain or lose at will and experience no difficulty in reducing their caloric intake. They are masters of their weight, which the obese are not. Moreover, their excess fat shows no preference for certain typical regions of the body, as does the fat in all cases of obesity. Thus, the decision whether a borderline case is really suffering from obesity or not cannot be made merely by consulting weight tables.

THE TREATMENT OF OBESITY

If obesity is always due to one very specific diencephalic deficiency, it follows that the only way to cure it is to correct this deficiency. At first this seemed an utterly hopeless undertaking. The greatest obstacle was that one could hardly hope to correct an inherited trait localized deep inside the brain, and while we did possess a number of drugs whose point of action was believed to be in the diencephalon, none of them had the slightest effect on the fat-center. There was not even a pointer showing a direction in which pharmacological research could move to find a drug that had such a specific action. The closest approach were the appetite-reducing drugs - the amphetamines - but these cured nothing.

A Curious Observation

Mulling over this depressing situation, I remembered a rather curious observation made many years ago in India. At that time we knew very little about the function of the diencephalon, and my interest centered round the pituitary gland. Froehlich had described cases of extreme obesity and sexual underdevelopment in youths suffering from a new growth of the anterior pituitary lobe, producing what then became known as Froehlich's disease. However, it was very soon discovered that the identical syndrome, though running a less fulminating course, was quite common in patients whose pituitary gland was perfectly normal. These are the so-called "fat boys" with long, slender hands, breasts any flat-chested maiden would be proud to posses, large hips, buttocks and thighs with striation, knock-knees and underdeveloped genitals, often with undescended testicles.

It also became known that in these cases the sex organs could he developed by giving the patients injections of a substance extracted from the urine of pregnant women, it having been shown that when this substance was injected into sexually immature rats it made them precociously mature. The amount of substance which produced this effect in one rat was called one International Unit, and the purified extract was accordingly called "Human Chorionic Gonadotrophin" whereby chorionic signifies that it is produced in the placenta andgonadotropin that its action is sex gland directed.

The usual way of treating "fat boys" with underdeveloped genitals is to inject several hundred International Units twice a week. Human Chorionic Gonadotrophin which we shall henceforth simply call HCG is expensive, and as "fat boys" are fairly common among Indians I tried to establish the smallest effective dose. In the course of this study three interesting things emerged. The first was that when fresh pregnancy-urine from the female ward was given in quantities of about 300 cc. by retention enema, as good results could be obtained as by injecting the pure substance. The second was that small daily doses appeared to be just as effective as much larger ones given twice a week. Thirdly, and that is the observation that concerns us here, when such patients were given small daily doses they seemed to lose their ravenous appetite though they neither gained nor lost weight. Strangely enough however, their shape did change. Though they were not restricted in diet, there was a distinct decrease in the circumference of their hips.

Fat on the Move

Remembering this, it occurred to me that the change in shape could only be explained by a movement of fat away from abnormal deposits on the hips, and if that were so there was just a chance that while such fat was in transition it might be available to the body as fuel. This was easy to find out, as in that case, fat on the move would be able to replace food. It should then he possible to keep a "fat boy" on a severely restricted diet without a feeling of hunger, in spite of a rapid loss of weight. When I tried this in typical cases of Froehlich's syndrome, I found that as long as such patients were given small daily doses of HCG they could comfortably go about their usual occupations on a diet of only 500 Calories daily and lose an average of about one pound per day. It was also perfectly evident that only abnormal fat was being consumed, as there were no signs of any depletion of normal fat. Their skin remained fresh and turgid, and gradually their figures became entirely normal, nor did the daily administration of HCG appear to have any side-effects other than beneficial.

From this point it was a small step to try the same method in all other forms of obesity. It took a few hundred cases to establish beyond reasonable doubt that the mechanism operates in exactly the same way and seemingly without exception in every case of obesity. I found that, though most patients were treated in the outpatients department, gross dietary errors rarely occurred. On the contrary, most patients complained that the two meals of 250 Calories each were more than they could manage, as they continually had a feeling of just having had a large meal.

Pregnancy and Obesity

Once this trail was opened, further observations seemed to fall into line. It is, for instance, well known that during pregnancy an obese woman can very easily lose weight. She can drastically reduce her diet without feeling hunger or discomfort and lose weight without in any way harming the child in her womb. It is also surprising to what extent a woman can suffer from pregnancy-vomiting without coming to any real harm.

Pregnancy is an obese woman's one great chance to reduce her excess weight. That she so rarely makes use of this opportunity is due to the erroneous notion, usually fostered by her elder relations, that she now has "two mouths to feed" and must "keep up her strength for the coming event." All modern obstetricians know that this is nonsense and that the more superfluous fat is lost the less difficult will be the confinement, though some still hesitate to prescribe a diet sufficiently low in Calories to bring about a drastic reduction.

A woman may gain weight during pregnancy, but she never becomes obese in the strict sense of the word. Under the influence of the HCG which circulates in enormous quantities in her body during pregnancy, her diencephalic banking capacity seems to be unlimited, and abnormal fixed deposits are never formed. At confinement she is suddenly deprived of HCG, and her diencephalic fat-center reverts to its normal capacity. It is only then that the abnormally accumulated fat is locked away again in a fixed deposit. From that moment on she is suffering from obesity and is subject to all its consequences.

Pregnancy seems to be the only normal human condition in which the diencephalic fat-banking capacity is unlimited. It is only during pregnancy that fixed fat deposits can be transferred back into the normal current account and freely drawn upon to make up for any nutritional deficit. During pregnancy, every ounce of reserve fat is placed at the disposal of the growing fetus. Were this not so, an obese woman, whose normal reserves are already depleted, would have the greatest difficulties in bringing her pregnancy to full term. There is considerable evidence to suggest that it is the HCG produced in large quantities in the placenta which brings about this diencephalic change.

Though we may be able to increase the dieneephalic fat-banking capacity by injecting HCG, this does not in itself affect the weight, just as transferring monetary funds from a fixed deposit into a current account does not make a man any poorer; to become poorer it is also necessary that he freely spends the money which thus becomes available. In pregnancy the needs of the growing embryo take care of this to some extent, but in the treatment of obesity there is no embryo, and so a very severe dietary restriction must take its place for the duration of treatment.

Only when the fat which is in transit under the effect of HCG is actually consumed can more fat be withdrawn from the fixed deposits. In pregnancy it would be most undesirable if the fetus were offered ample food only when there is a high influx from the intestinal tract. Ideal nutritional conditions for the fetus can only be achieved when the mother's blood is continually saturated with food, regardless of whether she eats or not, as otherwise a period of starvation might hamper the steady growth of the embryo. It seems that HCG brings about this continual saturation of the blood, which is the reason why obese patients under treatment with HCG never feel hungry in spite of their drastically reduced food intake.

The Nature of Human Chorionic Gonadotropin

HCG is never found in the human body except during pregnancy and in those rare cases in which a residue of placental tissue continues to grow in the womb in what is known as a chorionic epithelioma. It is never found in the male. The human type of chorionic gonadotrophin is found only during the pregnancy of women and the great apes. It is produced in enormous quantities, so that during certain phases of her pregnancy a woman may excrete as much as one million International Units per day in her urine - enough to render a million infantile rats precociously mature. Other mammals make use of a different hormone, which can be extracted from their blood serum but not from their urine. Their placenta differs in this and other respects from that of man and the great apes. This animal chorionic gonadotrophin is much less rapidly broken down in the human body than HCG, and it is also less suitable for the treatment of obesity.

As often happens in medicine, much confusion has been caused by giving HCG its name before its true mode of action was understood. It has been explained that gonadotrophin literally means a sex gland directed substance or hormone, and this is quite misleading. It dates from the early days when it was first found that HCG is able to render infantile sex glands mature, whereby it was entirely overlooked that it has no stimulating effect whatsoever on normally developed and normally functioning sex glands. No amount of HCG is ever able to increase a normal sex function; it can only improve an abnormal one and in the young hasten the onset of puberty. However, this is no direct effect. HCG acts exclusively at a diencephalic level and there brings about a considerable increase in the functional capacity of all those centers which are working at maximum capacity.

The Real Gonadotrophins

Two hormones known in the female as follicle stimulating hormone (FSH) and corpus luteum stimulating hormone (LSH) are secreted by the anterior lobe of the pituitary gland. These hormones are real gonadotrophins because they directly govern the function of the ovaries. The anterior pituitary is in turn governed by the diencephalon, and so when there is an ovarian deficiency the diencephalic center concerned is hard put to correct matters by increasing the secretion from the anterior pituitary of FSH or LSH, as the case may be. When sexual deficiency is clinically present, this is a sign that the diencephalic center concerned is unable, in spite of maximal exertion, to cope with the demand for anterior pituitary stimulation. * When then the administration of HCG increases the functional capacity of the diencephalon, all demands can be fully satisfied and the sex deficiency is corrected.

That this is the true mechanism underlying the presumed gonadotrophic action of HCG is confirmed by the fact that when the pituitary gland of infantile rats is removed before they are given HCG, the latter has no effect on their sex glands. HCG cannot therefore have a direct sex gland stimulating action like that of the anterior pituitary gonadotrophins, as FSH and LSH are justly called. The latter are entirely different substances from that which can be extracted from pregnancy urine and which, unfortunately, is called chorionic gonadotrophin. It would be no more clumsy, and certainly far more appropriate, if HCG were henceforth called chorionic diencephalotrophin.

HCG no Sex Hormone

It cannot he sufficiently emphasized that HCG is not a sex hormone, that its action is identical in men, women, children and in those cases in which the sex glands no longer function owing to old age or their surgical removal. The only sexual change it can bring about after puberty is an improvement of a pre-existing deficiency, but never a stimulation beyond the normal. In an indirect way via the anterior pituitary, HCG regulates menstruation and facilitates conception, but it never virilizes a woman or feminizes a man. It neither makes men grow breasts nor does it interfere with their

* As we are speaking of purely regulatory disorders, we obviously exclude all such cases in which there are gross organic lesions of the pituitary or the sex glands themselves.

virility, though where this was deficient it may improve it. It never makes women grow a beard or develop a gruff voice. I have stressed this point only for the sake of my lay readers, because it is our daily experience that when patients hear the word hormone they immediately jump to the conclusion that this must have something to do with the sex- sphere. They are not accustomed as we are, to think thyroid, insulin, cortisone, adrenalin etc, as hormones.

Importance and Potency of HCG

Owing to the fact that HCG has no direct action on any endocrine gland, its enormous importance in pregnancy has been overlooked and its potency underestimated. Though a pregnant woman can produce as much as one million units per day, we find that the injection of only 125 units per day is ample to reduce weight at the rate of roughly one pound per day, even in a colossus weighing 400 pounds, when associated with a 500-Calorie diet. It is no exaggeration to say that the flooding of the female body with HCG is by far the most spectacular hormonal event in pregnancy. It has an enormous protective importance for mother and child, and I even go so far as to say that no woman, and certainly not an obese one, could carry her pregnancy to term without it.

If I can be forgiven for comparing my fellow-endocrinologists with wicked Godmothers, HCG has certainly been their Cinderella, and I can only romantically hope that its extraordinary effect on abnormal fat will prove to be its Fairy Godmother.

HCG has been known for over half a century. It is the substance which Aschheim and Zondek so brilliantly used to diagnose early pregnancy out of the urine. Apart from that, the only thing it did in the experimental laboratory was to produce precocious rats, and that was not particularly stimulating to further research at a time when much more thrilling endocrinological discoveries were pouring in from all sides, sweeping HCG into the stiller back waters.
